Twitter is where I interact with the community.
Instagram is my most active social media.
GitHub is where I share my code.

I also have a page of links that lead to other people’s writing:

Essential Reading — links to several articles that have been important to my own thinking, and that you might be interested in reading if some of my own ideas have interested you.

Greatest Hits

“The Mighty Dictionary” Talk — My first big PyCon talk, and probably still my most popular.
“Pandas From the Ground Up” Tutorial — Hundreds of people have gotten started with the Pandas data library thanks to this tutorial, available as a YouTube video plus matching Jupyter notebooks. (Alas, the video also includes the conference coffee breaks.) I still keep the exercises up to date and make sure they work with the latest version of Pandas.
Python Design Patterns — A site where I’m writing up all of the old Gang of Four design patterns for Python programmers, weighing which ones are still useful in a modern dynamic language.
The Geology of the North Kaibab Trail — My first foray into earth science and cartography, this essay describes the rock layers that hikers traverse as they climb the Grand Canyon’s famous North Kaibab Trail.
Semantic Linefeeds — An essay advocating a practice from early in UNIX history: putting line breaks between sentences or phrases instead of when the line simply reaches a certain length, if you’re writing marked-up plain text that will be reformatted before the user reads it. The habit makes it easier to navigate, edit, and rearrange text.

Open-Source Software

You can see my full list of repositories on my GitHub account, but my most popular packages are:

Skyfield — A Python library that generates coordinates for stars, planets, and satellites using modern idiomatic conventions and the NumPy vector library.
PyEphem — My earlier foray into generating astronomy coordinates for Python. Still popular despite its awkward type conventions.
logging_tree — A small elegant companion for Python’s logging module. I am happy that one of my libraries, at least, still supports every Python version back to Python 2.3.

Foundations of Python Network Programming

I have twice revised the book Foundations of Python Network Programming for Apress Media. For the most recent Third Edition, I updated its code to Python 3 and expanded coverage of libraries like Requests, Paramiko, and ØMQ. I have made all of the book’s example code available in this GitHub repository:

All 108 Python example scripts from the book

Note that both of the links to the book (text and image) above are Amazon affiliate links, which generate a bit more income for an author than does an anonymous link — but you can also find the book through a quick search for its title.
